Grid Synchronizing Method Using 3-Level SVPWM of Grid Connected VSI

Renewable energy sources like wind, sun, and hydro are seen as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. Distributed power generation systems (DPGSs) based on renewable energy sources experience a large development worldwide. Due to the increasing number of DPGSs connected to the utility network, new and stricter standards in respect to power quality, safe running and islanding protection are issued. This paper analyzed the operation of synchronization grid connected VSI with the grid using SVPWM method. The paper also give an overview of synchronization methods and a discussion about their importance in the control
